Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Specified by:

getEdges in interface ITopologyNode

Parameters:

clockwise - The clockwise (in)

Returns:

A reference to a com.esri.arcgis.geodatabase.IEnumNodeEdge

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getDegree

public int getDegree()
              throws IOException,
                     AutomationException

The number of edges entering and leaving this node. Closed edges are counted twice.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:

getDegree in interface ITopologyNode

Returns:

The degree

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

isDegreeKnown

public boolean isDegreeKnown()
